Abstract: A display apparatus and an fingerprint sensing method thereof are provided. A display panel of the display apparatus has a pixel circuit array, an in-display touch sensor array, and an in-display fingerprint sensor array. A driving circuit drives the in-display fingerprint sensor array to read a fingerprint image. A current display frame period is divided into a plurality of unit periods, each of the unit periods includes at least one fingerprint sensing period and one or both of a display driving period and a touch sensing period. The driving circuit resets a current fingerprint sensor in the in-display fingerprint sensor array during a first fingerprint sensing period among these fingerprint sensing periods of the first display frame period. The driving circuit reads a sensing result of the current fingerprint sensor during a second fingerprint sensing period succeeding to the first fingerprint sensing period.

Abstract: An electronic device and a fingerprint sensing control method thereof are provided. The electronic device includes a touch control circuit and a fingerprint sensing control circuit. The touch control circuit is coupled to the display panel. The touch control circuit performs touch detection on the display panel to obtain a finger press area corresponding to the finger on the display panel. The fingerprint sensing control circuit is coupled to the touch control circuit to obtain a finger press area. The fingerprint sensing control circuit is coupled to the display panel to perform a fingerprint sensing control on a display panel. The fingerprint sensing control circuit scans the finger press area on the display panel in a first direction during a first period and scans the finger press area in a second direction different from the first direction during a second period after the first period.
